Molex (NASDAQ: MOLX) is a leading global supplier of electronic interconnectors. Molex sells over 100,000 products, including everything, from electrical and fiber optic interconnect solutions, to switches and application tooling^{[clarification needed]}. Molex supplies a variety of industries, including the telecom, datacom, computer and peripheral, automotive, premise wiring, industrial, consumer, medical and military markets.

Molex originated a large variety of connector types, but only one is commonly used in computer hardware, and thus is known unambiguously as a "Molex connector" in that context. That connector type is the one pictured, which is used for power connections for disk drives and other computer components. An AT or ATX standard 'power supply' normally has multiple connectors of this type.

A connector that delivers power has female pins in a male housing, as pictured; a connector that receives power has male pins in a female housing.

The company began by making flowerpots out of an industrial byproduct plastic called Molex. Later they made connectors for General Electric and other appliance manufacturers out of the same plastic. [1] Molex acquired Woodhead Industries^[when?] in the largest acquisition in its^[which?] history.
